DIOS/Uranium Discovery Confirmed on Hotish Godzila: 6 Samples Out of 8 Over 0.33 % Uranium Oxide, Up to 2.56 %

MONTREAL, QUEBEC--(Marketwire - Oct. 20, 2009) - DIOS EXPLORATION (TSX VENTURE:DOS) reports significant results from the Godzila uranium discovery recently made by DIOS during the 2009 Hotish systematic ground prospecting and exploration program. Out of eight basement rock samples taken on the zone, six returned grades over 0.33% U3O8 over an area of 25 m by 14 m, that is 2.56 %, 1.55 %, 0.722 %, 0.335 %, 0.502%, 0.33%, and also 0.13% uranium oxide.

Discovered in outcrops, the GODZILA showing appears as a 3-4 meters wide by 25 meters long (minimum) corridor. It consists of a fracture (mm-cm) system dominated by three main strikes and filled by quartz-magnetite-hematite and uraninite (uranium oxides) with small spots of uranophane. The thorium content is almost nil, another positive facet of this discovery.

A 25-meter long trench was dug with hand shovels. Eight grab samples were collected and sent to laboratories (ALS-CHEMEX and Saskatchewan Research Council) for assays, with standards and duplicates for quality control. Both extents of this showing remain open as they are covered by overburden. The discovery was made up-ice of a uranium lake bottom sediment anomaly.

These significant exploration results enhance the uranium potential of the DIOS wholly-owned Hotish uranium project, Otish Basin, QC. This discovery results from the work undertaken on only one of the seven prioritized targets identified on the Hotish property. More information will be released as soon as available.
